[英]SCP (using sshj) from remote HP-UX (Unix) server to local file system
[英]How to push the file content using SCP to a remote file directly from the local stream object to a remote file
如何使用 SCP 将文件内容直接从本地流对象推送到远程文件到远程文件,这样就不需要将文件临时存储在本地磁盘上?
目前我正在本地创建流并尝试直接推送到远程服务器,它能够成功建立会话,但是 channel.isConnected 变得错误,因为没有创建远程文件,请帮助。
Runtime rt = Runtime.getRuntime();
BufferedWriter out= new BufferedWriter(new FileWriter(f));
Process proc = rt.exec(cmd);
BufferedReader stdInput = new BufferedReader(new
InputStreamReader(proc.getInputStream()));
BufferedReader stdError = new BufferedReader(new
InputStreamReader(proc.getErrorStream()));
//Intiate SCP connection
JSch jsch=new JSch();
jsch.setConfig("StrictHostKeyChecking", "no");
Session session=jsch.getSession("userName", "scpServer", 22);
UserInfo ui=new MyUserInfo(); //Passing password from this class
session.setUserInfo(ui);
session.connect();
String rfile="/home/npachava/SCPTest/myTest.bson";
// exec 'scp -f rfile' remotely
String command="scp -f "+rfile;
Channel channel=session.openChannel("exec");
((ChannelExec)channel).setCommand(command);
System.out.println("session.getServerVersion()"+session.getServerVersion());;
System.out.println("session.isConnected() "+session.isConnected());
System.out.println("channel.isConnected() "+channel.isConnected());
// get I/O streams for remote scp
OutputStream outScp=channel.getOutputStream();
InputStream inScp=channel.getInputStream();
channel.connect();
// read the output from the command
System.out.println("standard output of the command:\n");
String s = null;
while ((s = stdInput.readLine()) != null) {
System.out.println(s);
out.write(s);
byte[] b = s.getBytes();
System.out.println("Bytes Length"+b.length);
outScp.write(b);
}
System.out.println("OutPutSCP"+outScp);
// read any errors from the attempted command
System.out.println("standard error of the command (if any):\n");
while ((s = stdError.readLine()) != null) {
System.out.println(s);
}
out.close();
outScp.flush();
outScp.close();
channel.disconnect();
session.disconnect();
}
我指的是http://www.jcraft.com/jsch/examples/ScpTo.java.html 中提到的例子
只需使用您的内存流而不是FileInputStream
。
在这一行( ScpTo.java
代码,而不是上面的代码)中,将您的“本地”流对象(例如ByteArrayInputStream
)分配给fis
,而不是创建FileInputStream
。
fis=new FileInputStream(lfile);
确保你首先从头开始寻找你的流。
